CARI-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 335,778, dated February9, 1886` Application filed September 12, 1885. Serial No. 176,864.

To all whom t may concern):

Be it known that I, ROBERT C. SoHENoK, .I r., a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements in Car-DoorLocks, of which the following is afull, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

My improvement relates to car-door locks composed of a staple and acorresponding hasp fitting thereon, and provided with a gravita-tinglatch, whereby when the hasp is fitted over the staple the gravitatinglatch piece falls to such a position that the hasp becomes at onceself-locked upon the staple.

The novelty of ny invention will be herein set forth, and specicallypointed ont in the claims.

In the accompanying drawings, Figure l represents a front elevation ofmy improved lock as applied to a car, showing the door locked entirelyshut and sealed. Fig. 2 is a central sectional view of my improved lockthrough the staple-plate and latch-piece.

The same letters of reference are used to indicate identical parts inboth the figures.

A represents a staple-plate attached to the side of the car B, andprovided with a projecting and preferably integral staple, C, overwhich. lits the hasp D, which is attached to the corresponding door, E,in the usual or any suitable manner.

Upon the staple C is loosely pivoted a gravitating latch-piece, F, whichis made heavier at one end, so that it always hangs in a substantiallyperpendicular position.

The position of the staple and hasp above described may of course bereversed-that is, the hasp may be hinged to the car and the staple beattached to the door. When it is The (No model.)

or may be locked ajar for the purpose of ventilation.

YVhile I prefer the form illustrated,wherein the upper portion of thelatch-piece is hollowed out, as shown, yet I do not limit myself to thedetails of form, but consider as the es-' sence of iny invention thecombination, with a preferably solid staple-piece, of a gravitatinglatch pivoted thereto and adapted to swing across the hasp to hold thesame locked against outward strain.

It will be observed that the ordinary and normal strain is bornedirectly by the staple O, and not by the gravitating latch.

I-Iaving thus fully described my invention, I claiml. Thecombinatiomwith a hasp, of a staple over which the hasp fits and withwhich it engages, and a gravitating latch pivoted to the staple andarranged to automatically swing across the hasp to hold the same locked,substantially as described.

2. The herein-described car-door fastening, consisting of the perforatedhasp D, staple plate A, having a staple, O, secured thereto, agravitating latch, F, pivoted to the staple C, and a bracket, G,projecting from the plate A, said latch and bracket being coincidentlyperforated to enable a locking-wire or padlock to be passedtherethrough, the whole constructed in the manner and for the purposespecified.
